Prefect is a workflow orchestration platform for automating, scheduling, and monitoring data pipelines, ML workflows, and AI agent operations. Its open-source core (Apache 2.0) turns plain Python functions into durable, observable workflows with a decorator, avoiding DAG-based config. Prefect Cloud adds managed/hybrid deployment, observability dashboards, and enterprise features (SLAs, SOC 2/HIPAA/GDPR compliance). It also offers FastMCP and Prefect Horizon for connecting AI agents to tools via MCP. Clients span startups to Fortune 500s, including Cash App, Ramp, Flatiron Health, NASA, and Cisco.
